Question

Which of the following statements regarding sertoli cell is correct?
A) It is found in seminiferous tubule and secrete testosterone hormone.
B) It is a place where spermatozoa is concentrated and stored until ejaculation.
C) It secretes spermatozoa activating substances like fructose, citrate, inositol, prostaglandin and protein.
D) It is found in seminiferous tubule and function as nurse cells for differentiating spermatozoa.

Answer 1

Hint: Seminiferous tubules are made up of sertoli cells, also known as sustentacular cells. They serve as nurse cells for spermatozoa differentiation, phagocytose damaged sperm, and release the hormone inhibin.

Complete Step by Step Answer:
The hormone testosterone cannot be produced by Sertoli cells.
The blood vessels and leydig cells that are present in the interstitial space between the tubules produce testosterone, which diffuses into the seminiferous tubules.
The male sex cells that contain a man's genetic material are called spermatozoa (sperm). They require a microscope to be seen since they are so little. One ejaculation from a healthy guy typically contains 40 million to 600 million sperm. Sperm have a long tail, a short midsection, and an oval-shaped head.
The complex process of morphological changes that occur in the seminiferous epithelium during sperm development. This mechanism causes significant structural and functional changes in haploid round spermatids, producing sperm that is highly polarised.
Hence, option D is the correct answer.

Note: Sperm are created in the testes. The vas deferens, which extends over the pelvic bone or ilium and loops around to the ampulla, seminal vesicle, and prostate, connects the testes to the other male reproductive organs.
